But what did Plato mean by essence, (Greek), which is the
intermediate nature compounded of the Same and the Other, and out
of which, together with these two, the soul of the world is
created? It is difficult to explain a process of thought so
strange and unaccustomed to us, in which modern distinctions run
into one another and are lost sight of. First, let us consider
once more the meaning of the Same and the Other. The Same is the
unchanging and indivisible, the heaven of the fixed stars,
partaking of the divine nature, which, having law in itself,
gives law to all besides and is the element of order and
permanence in man and on the earth. It is the rational principle,
mind regarded as a work, as creation—not as the creator. The old
tradition of Parmenides and of the Eleatic Being, the foundation
of so much in the philosophy of Greece and of the world, was
lingering in Plato’s mind. The Other is the variable or changing
element, the residuum of disorder or chaos, which cannot be
reduced to order, nor altogether banished, the source of evil,
seen in the errors of man and also in the wanderings of the
planets, a necessity which protrudes through nature. Of this too
there was a shadow in the Eleatic philosophy in the realm of
opinion, which, like a mist, seemed to darken the purity of truth
in itself.—So far the words of Plato may perhaps find an
intelligible meaning. But when he goes on to speak of the Essence
which is compounded out of both, the track becomes fainter and we
can only follow him with hesitating steps. But still we find a
trace reappearing of the teaching of Anaxagoras: ‘All was
confusion, and then mind came and arranged things.’ We have
already remarked that Plato was not acquainted with the modern
distinction of subject and object, and therefore he sometimes
confuses mind and the things of mind—(Greek) and (Greek). By
(Greek) he clearly means some conception of the intelligible and
the intelligent; it belongs to the class of (Greek). Matter,
being, the Same, the eternal,—for any of these terms, being
almost vacant of meaning, is equally suitable to express
indefinite existence,—are compared or united with the Other or
Diverse, and out of the union or comparison is elicited the idea
of intelligence, the ‘One in many,’ brighter than any Promethean
fire (Phil.), which co-existing with them and so forming a new
existence, is or becomes the intelligible world...So we may
perhaps venture to paraphrase or interpret or put into other
words the parable in which Plato has wrapped up his conception of
the creation of the world. The explanation may help to fill up
with figures of speech the void of knowledge.
